Mobile Computing enables information access anytime, anywhere. However, the needs of users and the constraints generated by the mobile environment raise the necessity to personalize access to services. This paper describes ICoMP (I-centric Communication Mobile Portal), which is a mobile portal that offers services based upon user profiles (these contain information including: preferences, available resources, location and environment context). Notably, ICoMP follows an I-Centric approach, whereby the system dynamically adapts to manage both user requirements and changes in the mobile environment. ICoMPrsquos infrastructure extends a reflective middleware (ReMMoC) with both context support, and an agent platform (Grasshopper) to improve access to information and application services. In this paper, we evaluate our implementation of the ICoMP portal in terms of memory footprint cost and support for mobile applications.
